What is the purpose of the Sump Tank in the Beach Unloading Assembly?

The purpose of the Sump Tank in the Beach Unloading Assembly is primarily to receive the initial purge of saltwater. When fuel is transferred from ships to shore, there is often a risk of saltwater contamination, which can occur due to the marine environment. The Sump Tank is strategically designed to capture this initial purge of saltwater before clean fuel continues through the system. By doing so, it helps to ensure that any contaminants do not enter the fuel distribution system, thereby protecting the integrity of the fuel and equipment involved in the unloading process.

This function is critical in tactical fuel operations, where maintaining the quality of fuel is crucial for operational readiness. The other options do not align with the primary role of the Sump Tank, as its main focus is on handling impurities rather than general storage, level monitoring, or fuel distribution.
